LAMP-EXTINGUISHER.

Specification of Letters Patent.

Patented July 16, 1907.

Application filed September 12, 1906. $erial No. 334,210.

To all whom it may concern:

Be it known that 1, CHARLES BERGENRR, a citizen of the United States,residing at Rochester, in the county of Mom'oe and State of New York,have invented a new and useful Improvement in Lamp-Extinguishers, ofwhich the following is a specification.

This invention relates to that class of lamp extinguishers whichcomprise a wick-supporting shelf or tray which can be placed atdifferent heights within the oil pot for regulating the period of timeduring which the wick is supplied with oil and the lamp is permitted toburn. Extinguishers of this type are used, for instance, in largetubular lamps, such as street lamps and side lamps, in which kind oflamps the oil pot is removable from the tubular frame in a sidewisedirection. In order to remove the oil pot the globe is pushed up intothe lamp top in which it remains sus pended. The wick-supporting shelfor tray is usually provided with a suspension bar by which it isadjustably suspended from the top of the oil pot and which projectsupwardly through said top and is located within the globe. Thissuspension bar interferes to a cer-,

tain extent with the introduction and removal of the oil pot and as itis surrounded by the globe, when the oil pot is in place in the lampframe, it is at times difficult to read the figures on the bar whichindicate the number of hours for which the lamp is adjusted to burn.

The object of my invention is to render the extinguisher more convenientin use.

.In the accompanying drawings: Figiu'e 1 is an elevation of a tubularstreet lamp provided with my improvement. Fig. 2 is a vertical sectionof the oil pot, on an enlarged scale. Fig. 3 is a side elevation of theoil pot at right angles to Fig. 2. Fig. 4 is a top plan view of the oilpot. Fig. 5 is a fragmentary horizontal section of the same in line 5-5,Fig. 2, on an enlarged scale.

' Like letters of reference refer to like parts in the several figures.

The frame of the tubular lamp comprises the top A, the side tubes 13 andthe lower air chamber 0 with V which the tubes connect and whichcontains the socket by which the frame is attached to the supportingpots D. E represents the globe and F the removable oil pot. The globerests upon a seat on the oil pot formed by an annular rim or flange fand is guided and held at its upper end in the top A of the frame.

Theoil pot is provided with a bottom air chamber 9 which receives theair from the bottom chamber C of the frame and from which the air passesthrough tubes it into the top air chamber 1' underneath the burner. Allof these parts may be of any usual or suitable construction.

K represents the tray, shelf or other device upon which the wick issupported and which can be adj ust ed up or down in the oil pot toregulate the period of time during which the lamp will burn. This wicksupport may be of any suitable construction but is preferably a platehaving perforations for the passage of the oil. I

L represents the suspension bar of the wick support K which is attachedto the latter at one side thereof and is arranged in a housing, chamberor recess 1 formed in the outer wall of the oil pot. This chamberprojects outwardly from the side wall of the oil pot and opens inwardlybetween the bottom m and the top plate at of the oil pot but is closedon the inner side above said top plate, as shown at p. This chamber isclosed at the bottom and open at the top and the suspension bar Lprojects above the same and is provided, preferably on its inner side,with projections or teeth q adapted to rest upon the top of the chamberand arranged at intervals corresponding with the different periods oftime for which the burning of the lamp is to be adjusted. The teeth aremarked with figures indi- Gating these periods. The chamber l and thesuspension bar L are arranged outside of the rim on which the globerests and so far from the same that the bar does not strike the globewhen the wick support has been raised to its highest position. As thesuspension bar of the wick support is arranged on the outside of theglobe it does not interfere with the insertion of the oil pot into thetubular frame or its removal therefrom, and the figures on the bar canbe readily seen when the oil pot is in place in the lamp frame. Theupright chamber or recess in the side of the oil pot affords aconvenient housing for the suspension bar without increasing the size ofthe oil pet.

I claim as my invention:

1. The combination of a tubular lamp frame, an oil pot 9O laterallyremovable therefrom and having at its top a globe seat and in its sidean upright chamber which projects outwardly from the side of the oil potand is open at the top outside of said globe seat, a wick support whichis vertically adjustable in said oil pot, and a suspension bar for saidsupport arranged in said chamber and projecting through the open topthereof outside of said globe seat, substantially as set forth.

2. The combination of an oil pot provided at its top with a globe seatand having in its side an upright chamher which projects outwardly fromthe side of the oil pot the oil pot, a wick support which is verticallyadjustable 10 and is open at the top outside of said globe seat, a wickin said oil pot, and a suspension bar arranged in said support which isvertically adjustable in said oil pot, and chamber and extendingupwardly from said support and a suspension bar for said supportarranged in said chamabove the top of said chamber, substantially as setforth.
